Title: Apparatus for delivering cut sheets
IPC: B65H29/68
Filed: 1962-05-21
Abstract: 985,227. Delivering sheets. JAGENBERG - WERKE A.G. May 21, 1962 [June 2, 1961; Nov. 13, 1961], No. 19425/62. Heading B6H. A device for overlapping sheets 4 cut from a paper web 1 by a rotary knife 3 comprises high speed conveyer belts 5, 6, which are driven at a rather higher speed than the linear speed of the web 1 so as to produce intervals between the sheets, and a low speed, perforated or porous conveyer belt 9 on which the sheets are overlapped and of which the upper run is disposed in a slightly lower plane than that of the belt 6. Between the belts 6, 9 the sheets are supported by a table 7, a roller 8 and a plate 18. Mounted above the right-hand end of the belt 9, Fig. 1, is a rotating compressedair nozzle 13 which is shielded over the greater part of its rotation by a jacket 14 having a downwards directed opening 15. Mounted beneath the upper run of the belt 9 is a suction box 16 carrying freely rotatable rollers 17 which support the belt 9. The nozzle 13 is driven from the knife 3 and suction is applied to the box 16 in synchronism with the action of the knife. A sheet 4 is carried at a high speed between belts 5, 6, passes over the plate 18 into the space between the belts 5, 9 and is lowered relatively slowly, owing to the presence of an underlying air-cushion, on to the belt 9 or the preceding sheet 4. When the trailing edge of the sheet is located above the plate 18 the nozzle 13 is aligned with the opening 15 in the jacket 14 and directs a blast of air at the trailing end of the sheet. Substantially simultaneously suction is applied to the suction box 16 and the cumulative effect of the two operations is that the trailing end of the sheet is forced firmly into contact with the belt 9 and is effectively braked so as to travel at the speed of that belt. The overlapped sheets are finally deposited on a stack 12. In modifications the nozzle 13 may be stationary, the air blast being controlled either by a perforated jacket rotatable around the nozzle and driven from the knife 3 or by a photo-cell which detects the intervals between the sheets as they pass over the belt 6. In another form, Fig. 5, the nozzle 13 is replaced by a rotary mechanical deflector 19 and the suction box 16 by brake bands 20 which may be stationary or driven in either direction.

Title: Pulse repetition rate selector
IPC: H04N5/10
Filed: 1956-06-29
Abstract: 792,700. Pulse discriminating circuits. STANDARD TELEPHONES & CABLES, Ltd. June 29, 1956 [July 1, 1955], No. 20161/56. Class 40 (6). A circuit for producing an output only in response to pulses of a predetermined repetition frequency comprises a pentode tube to the control grid of which positive input pulses are applied each of which produces a corresponding negative pulse on the screen grid which is passed down a short-circuited delay line having a tap intermediate the ends. The total delay time of the line from the input to the opposite end back to the tap being equal to the required pulse repetition period. The pulses produced at the screen grid are reflected as positivegoing pulses which are applied to the suppressor grid to cause a pulse of current to the anode on coincidence with a positive pulse at the control grid, the presence of a pulse of anode current produces an output signal. Fig. 1 shows a pulse repetition rate selector in which positive-going input pulses are applied to the control grid 12 of a pentode discharge tube 13 which is normally biased to cut-off at its control and suppressor grids. On occurrence of a positive input pulse a negative pulse is produced at the screen grid 15 which passes down the delay line 22 is inverted and appears back at the tap 25 on the line as a positive pulse which is applied to the suppressor grid of the tube. When coincidence occurs between the presence of a pulse at the input and at the suppressor grid a pulse of anode current is produced which shock excites the tuned circuit 27 which is tuned to the same frequency as the repetition rate of the desired pulses thus each subsequent anode pulse increases the amplitude of the oscillations of the tuned circuit until a maximum is reached and threshold device 28 is operated to produce an output signal.

Title: Improvements relating to the preparation of eggs
IPC: A47J43/14
Filed: 1929-07-02
Abstract: 340,543. Opening eggs. BEATTIE, A., The Coppice, Beach Avenue, Sanderstead, Surrey, and LYON, A. A., 14, Queen Victoria Street, London. July 2, 1929, No. 20276. [Class 28 (ii).] A machine for opening eggs has means .for feeding the eggs to the opening position, means for perforating the shells and means for widening the perforation to open the egg. As shown, the machine consists of an intermittent chain conveyer 2 having cross members 3 which support the eggs with their longitudinal axes transverse to the conveyer, a presser 13 which bears on an egg whilst it is penetrated by a double serrated blade 23, and means which separate the blade parts 23 thus breaking the shell and permitting the contents to fall into cups 35 carried on a chain conveyer 37 running at right angles to the conveyer 2. The members 3 may be rollers and may be reel-shaped. The presser 13 is mounted on a pivoted lever 14 connected to a spring 15 which tends to disengage the presser. The lever 14 has an inclined surface or rack of shallow depressions 16 on its upper face, the surface .16 being engaged by a block 17 on a shaft 18 which is moved clockwise by a spring 19. The shaft 18 also carries a lever 22 which abuts against a bell crank 21 and acts as a stop to prevent the spring 19 from actuating the block 17 to depress the presser 13 when no egg is in the position for opening. When an egg is correctly positioned, the bell crank 21 is moved by a cam on the shaft 11 and the presser 13 descends. The knives 23 are each carried on an arm 32 having a toothed quadrant at its lower end. The arms 32 are thus intergeared and the knives are normally kept together by a tension spring joining the arms. The arms are pivoted on a lever which is cam actuated, so that when an egg is held under the presser 13, the lever is raised to lift the knives against the shell. Cam means then actuate the arms 32 to separate the knives. The contents of the eggs are dropped from the cups 35 into a shoot 41 the upper end of which may be movable out of the way of any bad egg which is detected. The shoot 41 has a narrow slot through which the whites pass on to a lower shoot. The yolks can thus be separately collected. The cups 35 are cleaned by a water or steam spray 42.
